These conditions can often be confused, but there are a few differences between a food allergy and a sensitivity that you should be aware of. Here are some indications to help differentiate between the two conditions:

Food Allergy Symptoms

  • Appear immediately
  • Involve an immune system response
  • Small amounts of a food can trigger a big reaction
  • A reaction occurs every time a specific food is eaten
  • The situation may become life-threatening if the response is severe.

Food allergies can present very serious, sometimes life-threatening symptoms. The following symptoms can turn serious very quickly if left unattended,

  • A rash, or hives may appear that causes the area to itch
  • Shortness of breath due to swelling of the bronchial tissue in the lungs
  • Difficulty swallowing caused by a swollen larynx
  • A swollen tongue
  • Chest pain accompanied by a change in blood pressure

When and if an individual in Ottawa begins to feel chest pain, difficulty in breathing and/or swallowing, call 911 immediately.

Food Intolerance Symptoms

  • Appear gradually
  • Involve a digestive system response, but can also involve other body systems
  • Takes place when large servings are eaten
  • The reaction will never be life-threatening

For people with a food sensitivity or intolerance, the body is unable to process or digest the food correctly. The following symptoms may occur:

  • Heartburn
  • Cramps, bloating, or gas
  • Headaches
  • Nervousness, or Irritability

Shared Symptoms of both Intolerance and Allergy May Include:

  • Abdominal discomfort
  • Vomiting
  • Diarrhoea
  • Nausea
